Abstract: Among the present generation of multiphysics HPC simulation codes there are
many that are built upon general infrastructural frameworks. This is especially
true of the codes that make use of structured adaptive mesh refinement (SAMR)
because of unique demands placed on the housekeeping aspects of the code. They
have varying degrees of abstractions between the infrastructure such as mesh
management and IO and the numerics of the physics solvers. In this experience
report we summarize the experiences and lessons learned from two of such major
software efforts, FLASH and Chombo.
